Claim of US Patent No. 11,115,960


1. A terminal apparatus for communicating with a base station apparatus, the terminal apparatus comprising:a transmitter configured to transmit a physical uplink shared channel (PUSCH); and
a receiver configured to receive radio resource control (RRC) information, wherein
the RRC information includes timeout period for transmission of the PUSCH, and a number of hybrid automatic repeat requests (HARQ) processes in a pre-allocated radio resource,
the resource information for the transmission of the PUSCH includes symbol information for the transmission of the PUSCH, and
the pre-allocated radio resource is shareable among a plurality of terminal devices; and
a controller configured to determine a HARQ process ID based on at least a symbol index for the transmission of the PUSCH and the number of HARQ processes,
the transmitter transmits the PUSCH by using a resource associated with the HARQ process ID irrespective of downlink control information, the resource being a portion of the pre-allocated radio resource, and
in a case that the receiver receives no response to the transmission of the PUSCH with the HARQ process ID after the transmission of the PUSCH is performed and before the timeout period expires, the transmitter transmits the PUSCH by using the resource associated with the HARQ process ID.
